DNA which doesn't carry the information to make proteins. Originally thought to be "junk", but people are finding that it does have functions.

Noncoding portion of DNA is composed of?
A noncoding portion of DNA is called an intron, and is composed of codons that will eventually be removed after transcription when the final mature strand of mRNA is produced.
What is Heterogeneous nuclear DNA?
Pre-mRNA. It is the mRNA that is synthesized in the nucleus of eukaryotes. After being synthesized, this mRNA is processed, so that introns, noncoding, DNA is removed.
Do two DNA strands need to be separated before DNA replication or transcription can occur?
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
What is the part of a strand of DNA with regulatory sequences?
Noncoding gene sequences control gene expression. You may also be thinking of what is called "junk DNA" which is not junk. We just do not know what all of it codes for.
What is the difference between an intron and exon?
Exons code for amino acids (they are usable codons) Introns code for nothing.
What is the significance of noncoding DNA to DNA identification?
the significance of noncoding DNA to DNA identification is to drive main evoloutionary changes like the developement of unique human parts
Noncoding portion of DNA is composed of?
A noncoding portion of DNA is called an intron, and is composed of codons that will eventually be removed after transcription when the final mature strand of mRNA is produced.
What is satellite DNA?
Satellite DNA is a noncoding region of DNA that is repeated many times. It is mainly located in the centromere.
Do exons contain noncoding DNA?
no because the introns have no function in protein synthesis
What is Heterogeneous nuclear DNA?
Pre-mRNA. It is the mRNA that is synthesized in the nucleus of eukaryotes. After being synthesized, this mRNA is processed, so that introns, noncoding, DNA is removed.
Why is the outdated term junk DNA a misnomer for noncoding regions of the human genome?
The conservation of "junk DNA" sequences in diverse genomes suggests that they have important functions.
Do two DNA strands need to be separated before DNA replication or transcription can occur?
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
What is the noncoding segment of a gene?
There are many different parts of the gene that are noncoding. some main ones are introns, which just pretty much fill up DNA space, and gene expression regulators, which regulate the expression of genes. (operators, promoters, etc.)
What is the most likely reason why the cricket genome has 11 times as many base pairs as that of Drosophila?
Because Cricket have more noncoding DNA
What is the part of a strand of DNA with regulatory sequences?
Noncoding gene sequences control gene expression. You may also be thinking of what is called "junk DNA" which is not junk. We just do not know what all of it codes for.
Why are genetic markers from noncoding regions useful in distinguishing DNA fingerprints?
To use DNA to identify a specific person accurately, you want to compare genetic markers that are unlikely to be shared with any other person.
What is the difference between an intron and exon?
Exons code for amino acids (they are usable codons) Introns code for nothing.
